This study's purpose is to systematically review the literature to identify the most recent library practices against fake news. Libraries are perceived as an important player against the fake news phenomenon. However, this role is often cornered in a positive self-perception of the work of librarians. This article investigates the tangible practices of libraries, discusses their efficiency, and provides a categorization of those practices. It was performed a systematic literature review of the last three years to retrieve the most recent library practices. After the extraction, with a final set of 27 documents, a multi-step qualitative analysis and a categorization were developed. Findings show most studies emphasize academic libraries practices and are mainly focused on information literacy instruction. The current debate is around strategies that intend to reiterate an authority-based source evaluation versus the challenge to recognize an emotional-based reaction to fake news in a post-truth world, and the need to scout libraries' new routes.

The production of large volumes of scientific information, considering its cost, requires approaches that ensure its maintenance, reuse and recovery. These concerns prompted the emergence of digital curation. We intend to discuss the relevant thinking concerning the costs of digital curation. This means addressing the definition of the concept and the issue of costs, based on the studies related to cost models. A literature review was conducted using B-On and RCAAP as research sources, exploring the perceptions of the authors regarding the digital curation and its costs. The views expressed were organized around a scheme based on the Digital Curation Centre (DCC) lifecycle and the reference model Open Archival Information System (OAIS). It is proposed a systematization of digital curation issues bridging the DCC life cycle view of the digital object curation to the OAIS reference model approach, using a cross view seized by cost models and plan/data management policies.

This study’s purpose is to systematically review the literature to identify the most recent library practices against fake news. Previous findings showed most studies emphasize academic libraries practices and are mainly focused on information literacy instruction. This article updates prior research aiming to acknowledge the tangible practices of libraries, discuss their efficiency, and continue a categorization of those practices. It was performed a systematic literature review of the last 12 months (October 2020-September 2021) to retrieve the most recent library practices. After the extraction, with a final set of 17 documents, a multi-step qualitative analysis, and a categorization were developed. The current debate is still around information literacy strategies that intend to reiterate an authority-based source evaluation versus the challenge to recognize an emotional-based reaction to fake news in a post-truth world. The role of libraries is cornered in an instructional framework, while disinformation is pervasive in several information ecosystems. The role of libraries in a Post-truth society is still an open debate, yet there is almost a consensus that libraries should engage in partnerships and be part of a multidisciplinary approach.
